Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446226, here are decompositions:

3 + 31446223 = 31446226
59 + 31446167 = 31446226
173 + 31446053 = 31446226
269 + 31445957 = 31446226
503 + 31445723 = 31446226
563 + 31445663 = 31446226
653 + 31445573 = 31446226
683 + 31445543 = 31446226

Showing the first eight; more decompositions exist.
